[bug\_fix] go: module github.com/foo/[email protected] found, but does not contain package github.com/foo/bar/Utils

Correct the case of the import path to match the exact directory name in the upstream repository \(e.g., change /Utils to /utils\). Go module paths are case-sensitive.

Journey Context:
A developer imports what they think is 'github.com/foo/bar/Utils' based on an IDE autocomplete or README. 'go mod tidy' downloads the module 'github.com/foo/bar' successfully but then fails, claiming the package doesn't exist. They check GitHub and see the directory is named 'utils' \(lowercase\). Because Go module paths strictly enforce case sensitivity to ensure reproducible builds across case-insensitive file systems like macOS/Windows, the Go toolchain refuses to match 'Utils' to 'utils'. They correct the import path in their code to 'github.com/foo/bar/utils', and the build succeeds.
